L’étude de l’évolution du droit international face aux risques posés par les accidents nucléaires soulève une série de questionnements. Le premier est relatif aux moyens juridiques par lesquels le droit entend faire face aux risques et à leur matérialisation. Le second va s’attacher à apprécier l’efficacité et l’effectivité du droit adopté. Enfin, en postulant d’un relatif échec du droit suite à la survenance des accidents nucléaires, il faut encore s’interroger sur les possibilités d’amélioration du droit. Ces différentes interrogations peuvent être rassemblées sous la question plus générale de la pertinence de l’adaptation du droit international face au risque nucléaire. Plus largement, la thèse qui émane de ces travaux est celle d’une adaptation continue du droit, issue de la dynamique dialogique existant entre la science juridique et le progrès scientifique, comme un gage d’une amélioration de son efficacité et de son effectivité. Cette adaptation est toutefois dépendante de l’évolution technique de l’énergie nucléaire. En effet, l’atome va à la fois limiter et étendre la portée même de ce droit. Cette caractéristique originale, laisse entrevoir la présence de difficultés au sein de l’ambitieuse mission consistant à appréhender le fait scientifique dans toute sa complexité. L’enjeu est de taille pour le droit nucléaire international : il s’agit de pallier les effets d’un risque technologique majeur afin de préserver les conditions de vie de l’humanité / Reviewing the complex relation between international law and nuclear risks posed by major accidents raises a set of questions. It first addresses the nature of the legal response made in this regard. It also appreciates whether the framework is sufficiently efficient and effective. At last, assuming that nuclear accidents turn international law into a relative failure, it is worth exploring different means to enhance the said law. Simply put, this brings us to the question of whether the adaptation of international law to nuclear risk is relevant. More broadly, our thesis consists in defending that continuous adaptation of law, resulting from the dynamic dialogue between legal science and scientific progress, improves its efficiency and effectiveness. However, the adaptation widely depends on the technological development of nuclear energy, as the atom both limits and extends the scope of international law. This original feature reveals that many difficulties arise when it comes to grasp the complexity of scientific facts. The stakes are high as international nuclear aims at mitigating the effects of a major technological risk in order to preserve the living conditions of mankind

Thesis (M.Sc. (Statistics)) -- University of Limpopo, 2020 / Background: Death and economic losses due to road traffic accidents (RTA) are huge global public health and developmental problems and need urgent attention. Each year nearly 1.24 million people die and millions suffer various forms of disability as a result of road accidents. This puts road traffic injuries (RTIs) as the eighth leading cause of death globally and RTIs are set to become the fifth leading cause of death worldwide by the year 2030 unless urgent actions are taken. Aim: In this paper, we investigate factors that contribute to road traffic deaths (RTDs) in the Limpopo province of South Africa using models such as the generalized linear models (GLM) and zero inflated models. Methods: The study was based on retrospective data that comprised of reports of 18,029 road traffic accidents and 4,944 road traffic deaths over the years 2009 – 2015. Generalized linear modelling and zero-inflated models were used to identify factors and determine their relationships to RTDs. Results: The data was split into two categories: deaths that occurred during holidays and those that occurred during non-holiday periods. It was found that the following variables, namely, Monday, human actions, vehicle conditions and vehicle makes, were significant predictors of RTDs during holidays. On the other hand, during non-holiday periods, weekend, Tuesday, Wednesday, national road, provincial road, sedan, LDV, combi and bus were found to be significant predictors of road traffic deaths. Conclusion: GLM techniques, such as the standard Poisson regression model and the negative binomial (NB) model, did little to explain the zero excess, therefore, zero-inflated models, such as zero-inflated negative binomial (ZINB), were found to be useful in explaining excess zeros. Recommendation: The study recommends that the government should make more human power available during the festive seasons, such as the December holidays, and over weekends.

The purpose of this study is to gather and to present information on the liability structure of our legal system in such a manner as to help the classroom teacher to understand more fully his legal responsibilities and thus relieve him of unwarranted fears regarding accidents and injuries resulting from classroom activities. It is hoped that this study will ultimately contribute to the security of those who read it and give encouragement to those who seek to enrich their classes by means of the experience type curriculum. / Typescript. / "A Paper." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Science." / "August, 1956." / Advisor: Edna E.

In December 1978, United Airlines Flight 173 arriving in Portland from Denver with 189 people aboard crash-landed in a suburb at 157th and East Burnside. Ten people were killed and dozens more were injured. The jet ran out of fuel after it had circled for an hour while the crew tried to determine what was wrong with the right main landing gear, which had fallen with a huge double jolt on extension. The investigation that followed the crash placed the blame squarely on the pilot for his negligence in failing to monitor his fuel supply, and secondarily on his crew members, who failed to adequately communicate their concerns about it. The accident was a watershed event in what would become known in the airline industry as crew resource management, a communication model designed to reduce human error by fostering collaborative decision-making and assertiveness training. In the years that have followed the accident, very little has changed in the narrative surrounding it. Articles and docudramas on the plane crash consistently repeat the tale as is, blaming the pilot and shedding no light on the factors that led to the in-flight emergency or on United's role in contributing to the crash. This thesis is a "cold-case" investigation that reveals those contributing factors, which have been so thoroughly ignored. In the words of renowned attorney F. Lee Bailey, "The rule of law requires that all parties who contribute to an accident share in the responsibility for whatever harm has been caused." This is the untold story of all the decisions that brought down United Flight 173, and of the responsibilities heretofore overlooked.

Thesis (M.A. (Communication Studies)) -- University of Limpopo, 2017 / The use of communication technologies has brought changes to our daily ways of doing things. Youth use technology for different purposes at different locations. As technology grows everyday with various advantages, its benefits come along with some disadvantages. Road accidents are one of the major problems that South Africa experiences. The focus of this study was to explore the danger of texting and driving and its potentials for road accidents. This research focused on the negative impact of technology, mainly technological distraction, while driving. Broadly, this research looks at the social and cultural impact of texting and mobility, with specific focus on distracted driving. This study is significant in the social analysis of technology use and distraction; this significance is made more important considering that there is very limited study of this social issue in South Africa. The always-available communication culture (such as texting while driving) should be viewed as a problematic phenomenal. For data collection, the researcher conducted a survey with adults and youth drivers to explore the perceptions and attitudes of drivers towards cell phone use, texting and driving. The researcher also conducted roadside observations of drivers to investigate the occurrence of distracted driving due to technology use, and interviews were conducted with Traffic Officers to share their professional experience on observing incidences of texting and driving. The study reveals that technology use, texting and driving is a common problem among young drivers, while adults tend to be more careful and engage less in this activity. Aspect of the findings of the study shows that 60% of drivers report that they have sent a text while driving. Moreover, the study explores ways of curbing cell phone use texting and driving on South African roads. There should be more research on distracted driving and technology use, so that more suggestions on how to curb technology use while driving can be offered

Though the trucks consist of only 3% of the total registered vehicles in the United States, truck accidents have been a major concern due to the property damage and loss of lives involved. Growth trends show that the truck travel will reach 1 trillion vehicle miles by the end of the year 2000. This increase in truck travel poses a major threat to the safety of both passenger cars and trucks. To improve the safety of the trucks as well as the passenger cars, understanding of the factors affecting the truck safety is essential. Models developed in the past were mostly regression models which tried to relate the truck accidents to the geometry of the highways. But most of these models did not consider all the factors affecting the safety of the trucks. Simulation models were developed in the past to study the dynamic vehicle response to different highway geometry especially, on exit ramps where most of the rollover accidents occur every year. But not enough research was done in the past on the weather and surface conditions affecting the truck safety. The objective of this study is to develop a graphics-based computer simulation model to test the trucks for different geometric features, surface conditions, and truck characteristics on exit ramps and to gain a better understanding of the factors affecting the safety of the trucks. A high-level simulation language SIMSCRIPTII.5 was used in the study to develop a simulation model. To make the model is to understand, graphical windows and animation were included in the model. Three exit ramps were tested in this model. Two of these ramps are existing ramps in southwestern Virginia and they had rollover accidents reported on them in the past. The parameters and other surface and geometric conditions can be changed at any time during the simulation. The model indicated that deceleration lengths provided may not be sufficient for heavy trucks traveling at higher speeds to reduce their speeds to the safe speed limits on the ramps. The posted speed limits may not be suitable for heavy trucks especially when the surface is not dry. The model also indicated that the tractor-semitrailers are more exposed to rollovers than any other type of trucks. / Master of Science

Thesis (M.Tech.: Chiropractic)-Dept. of Chiropractic, Durban Institute of Technology, 2006 129, [21] leaves / The first objective was to investigate the injury profiles of South African cyclists, especially those relating to mountain bicycle use on the road, as there appears to be no knowledge available on mountain bicycle use on the road and related injuries. Secondly, to see if there is an association between injuries and bicycle set-up in a South African context.

Dissertation submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic in the Department of Chiropractic at the Durban Institute of Technology, 2006. / The aim or purpose of this study is to determine the injury profile of gymnasts in the greater Durban area of KwaZulu-Natal, South Africa; and to compare it with the international data that are available. Factors that should be considered regarding differences in the injury profile of South African gymnasts as compared with international gymnasts include: 1. Difference in standard of gymnastics (Cameron-Smith, 2005) 2. Sudden increase in the standard of South African gymnastics in an attempt to match that of other countries, which may lead to an increase in training hours, and attempts at more risky new manoeuvres. This, in turn, may increase the risk of injury (Cameron-Smith, 2005). For the purpose of this study, the following information was gathered in terms of: - Demographics of South African gymnasts - The participants’ gymnastics history - The presence of any past or current injuries, and - If present, factors relating to these injuries were investigated. This information mentioned above was gathered with the aim of helping to identify any problems that may exist, quantifying the extent of these problems and identifying to some extent the potential risk factors. This would be beneficial to South African gymnasts if recommendations for prevention of potential injuries were made, should any common injuries, or possible risk factors or associations be discovered/identified (Chadwick, 2004).
